PRO SPER ALEXANDRE RENAUX, OF PARIS, FRANCE.

DRIVING MECHANISM FOR MOTOR-CYCLES OR MOTOR CARS.

SPECIFICATION forming part of Letters Patent No. 661,816, dated November 13, 1900.

Application filed October 23, 1899. Serial No. 734,527. (No model.)

- cycles or Motor-Oars, (for which I made application for Letters Patent in France on the 26th day of September, 1899,) of which the following is a specification.

This invention relates to an arrangement of motor mechanism adapted to anexplosion engine or motor and particularly applicable to motocycles and automobile vehicles. The chief feature is that the explosion-motor operates the driving-axle by means of a special arrangement which takes the place of a differential gear for the motor-axle. This special arrangement effects its object under conditions particularly advantageous with respect to solidity and avoids all risk of the gearing getting out of order.

I do not ignore the gear known under the name of differential nor its different applications and modes of employment; but face to face with known arrangements my mechanical combination effectsthe transmission of the motive power in a most efficacious and satisfactory manner and gives a better utilization of the motive force than heretofore.

I will now describe my motor mechanism, reference being had to the accompanying drawings, in which Figure l is a longitudinal section taken on the axis of the cylinder and that of 'the motor-shaft. Fig. 2 is a section on the line 2 2 of Fig. 1, and Fig. 3 is a section on the line 3 3 of Fig. l.

a and b are two shafts forming part of the motor shaft, which operates the drivingwheels directly or by any suitable intermediary mechanism if there is any necessity for the reduction of the speed. On these two shafts a and b are mounted loosely two fiy-wheels c and d, between which works the head of a connecting-rod c. This rod 6 is pivoted in any convenient manner to the piston f,which works in the motor-cylinder g. This cylinder is fixed at its front end to a box or carrier h, in which the two fiy-wheelsbefore named are inclosed and in the walls of which also are the bearings for the shafts a and b.

It is unnecessary to describe the difierent organs of the motor-such as admission and exhaust valves, &c., arrangement for evolving, and so onwhich may vary according to the fancy of the manufacturer and form no part of the present invention, which applies only to the means for conveying the power derived from the motor to the drivingwheel axle. The head or strap c of the connecting-rod e is mounted on a sleeve j, situated between the two fly-wheels c d and acting as a crank-pin. a wide spur-pinion is Z, mounted loosely on a short axle m, carried by and connecting the two fly-wheels. This pinion at its part is in gear with the spur-wheel 'n, which is keyed ,on the shaft b and projects through a slot in the sleevej for the purpose, and at its partl with a loose pinion 0, which also projects through a slot in the sleeve. This pinion o is suitably carried by the fly-wheel c and is in gear with the spur-wheel p, keyed on the axle a. Such an arrangement of mechanism is very strong and reduces to a minimum the difierent parts of the motor mechanism of an automobile vehicle.

I claim- 1. Adriving mechanism for automobile carriages, comprising two shafts, a fly-wheel loosely mounted on each of them, a sleeve connecting the fly-wheels, a pinion contained in said sleeve, a pinion rigidly mounted upon .each of said shafts, one of these pinions enwheels and connecting, the gear-wheel with In this sleeve is placed the other pinion, and operating mechanism 7 having connection with the sleeve.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
